[ Detailed description ] of the invention
Example 1
Referring to fig. 1-3 of the specification, the invention discloses a rotatable sealing head lifting device, which comprises a main rod frame 1 and two clamping arms 2 used for clamping the outer wall of a sealing head 5, wherein the two clamping arms 2 are respectively connected with two ends of the main rod frame 1 through rotary hinges, the included angle between the clamping arms 2 and the main rod frame 1 is adjustable within the range of 45-180 degrees, the sealing heads with various specifications can be adapted by adjusting the included angle, the lifting device does not need to be matched independently, the operation is convenient, and the cost is reduced.
The lifting lugs 3 are welded on the clamping arms 2, the number of the lifting lugs 3 is at least two, the lifting lugs 3 are respectively arranged at two ends of the clamping arms 2 at one side of the main rod frame 1, stress points are transferred to the lifting device, so that the quality problem of cracks generated when the lifting lugs are welded on the sealing head 5 is avoided, and in addition, the lifting lugs 3 are designed at two ends of the clamping arms at the same side, so that the sealing head can be conveniently turned over and lifted, and then can be conveniently covered on new equipment.
The device further comprises a lifting hook 4 for hooking the inner wall of the sealing head, the lifting hook 4 is L-shaped, the lifting hook 4 is connected to the lower portion of the main rod frame 1, the lifting hook 4 stretches into the inner hole wall of the sealing head 5 when being lifted, the inner wall of the sealing head is hooked, a rubber pad 41 is arranged on the contact surface between the lifting hook 4 and the inner wall of the sealing head, and the setting of the lifting hook 4 can ensure that the firmly lifted sealing head is not fallen.
The contact surface between the clamping arm 2 and the outer wall of the seal head 5 is composed of two inclined planes 21, and the included angle formed between the two inclined planes 21 is adjustable. The arrangement of the two inclined planes can ensure that the two inclined planes are in contact with the sealing heads of different specifications, and the outer wall of the sealing head is round and can be better clamped through the angle adjustment between the two inclined planes, so that the stability during lifting is ensured.
The contact surface between the clamping arm 2 and the outer wall of the seal head 5 is provided with a rubber pad, so that the outer wall of the seal head can be prevented from being scratched.
The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, but any modifications, equivalent substitutions, improvements, etc. within the spirit and principles of the present invention should be included in the scope of the present invention.
